Air curtain: Berner International Corp.

Berner International Corp. has added single-length 7-, 8-, 9-, and 10-ft long models to its ANSI/NSF 37-certified E-Zone and K-Zone (EZN and KZN Series) air curtains designed for energy savings and flying insect control. The EZN and KZN Series are now available in nine widths ranging from 3 ft to 10 ft, which the company says eliminates the inconvenience and mismatches of combining smaller sizes to create a longer air curtain.

The air curtains are made in the U.S. and are designed for various applications including walk-in coolers, pass-thru windows, concession windows, patio openings, service/customer entry doors, and other doorways that need environmental control in the foodservice, dock-and-door, and HVAC/R markets.

ANSI/NSF 37-certification ensures each model has been tested to surpass every state health code requirement for protecting all restaurant and foodservice establishment doorways.

Engineered Systems magazine’s May 2020 issue examines the revitalization of air-cooled chillers in data center facilities, the viability (or lack thereof) of duct systems, the impact the coronavirus is having on the built environment, and much more.
